Vswitch Port Data Type sorting

Generally, a vswitch has multiple Ethernet (physical) ports, and each port can be configured as needed to implement different functions. The vswitch itself has multiple VLANs (usually the default VLAN is 4094 ). VLAN is only a virtual division. Physical transmission must be specified to a specific Ethernet port. The Ethernet port has three links.

EthernetPortThere are three linksType: Access, Hybrid, and Trunk. AccessTypeOfPortIt can only belong to one VLAN and is generally used to connect to a computerPort; TrunkTypeOfPortIt can belong to multiple VLANs and can receive and send packets from multiple VLANs.VswitchConnectedPort; HybridTypeOfPortIt can belong to multiple VLANs and can receive and send packets from multiple VLANs. It can be usedVswitchCan also be used to connect to a user's computer.

HybridPortAnd TrunkPortThe difference is that HybridPortYou can allow packets of multiple VLANs to be sent without tags, while TrunkPortOnly packets of the default VLAN can be sent without tags.

Note that:

1. On an EthernetVswitchUp, TrunkPortAnd HybridPortCannot be set at the same time.

2. IfPortSpecified as imagePortAnd cannot be set to Trunk.PortAnd vice versa. By default,PortFor AccessPort.

PortReceiveDataTime: IfPortIs in tagged mode, whenDataIf the package itself does not contain VLANDataThe default vlan is added to the package. IfDataIf the package already contains a VLAN, it will not be added.

In the untagged modeDataThe default vlan must be added to all packages.DataWhether the package has VLAN tags.

PortSendDataTime: IfPortIs in tagged mode. IfPortThe default VLAN is equal to the sentDataThe VLAN contained in the package, the VLAN will be marked fromDataRemove from the package; if not equalDataThe packet will be sent out with the VLAN To implement transparent transmission of the VLAN.

In the untagged modePortThe default VLAN value, whether it is equal to the value ofDataThe vlan id of the packageDataPackage removed.

Tagged generally uses vlanVswitchCascade, untagged is used to connect to the PC.

TaggedPortGenerally, it is a relay.Port, That isVswitchConnectionPort. UntaggedPortGenerallyVswitchConnected to the terminalPort.

In the BigHammer6800 SeriesVswitch,PortIt can belong to multiple VLANs in Tagged mode, but onePortYou can only belong to one VLAN in the Untagged mode.
